Having a hard time trying to get pregnant? You might want to consider the woman’s blood type, as it may have an effect on her chances of conceiving.
A group of researchers from the Albert Einstein College of Medicine studied some 560 women, average age 35, who were undergoing fertility treatment, finding out that those with blood type O may have difficulty conceiving.
It was discovered by the researchers, led by Dr. Edward Nejat, that women with blood type O were twice as likely to have abnormally high levels of follicle-stimulating hormones, or FSH. FSH is responsible for giving the signal to the ovaries to create more eggs. With age (30s and 40s) and lowered egg production, the FSH level increases, indicating less and lower quality eggs. On the other hand, women with blood type A were found to have a higher number and quality of eggs.
"It's a very interesting finding, but I don't think anybody should hit the panic button if they're type O," said Dr. Elan Simckes of Fertility Partnership in St. Louis. The findings, though, if confirmed, may urge women with blood type O to get pregnant at an earlier age.
"A woman's age remains the most important factor in determining her success of conceiving,” said Nejat. “The baseline FSH gives us an idea of the quality and quantity of a woman's eggs."
Other fertility tests, though, were not taken into consideration for the study, such as the Antral follicle counts test and the anti-Mullerian hormone fertility test.
